Subject [GitHub] flink issue #3712: [FLINK-6281] Create TableSink for JDBC.
Date Tue, 20 Jun 2017 14:50:09 GMT

    Yes, I think that would work well. We could provide a builder for the table source and
forward calls to the `JDBCOutputFormatBuilder`. 
    
    Regarding the query template: we can also make it an optional parameter to override the
standard `INSERT INTO ... VALUES` template if set. 
    
    If you want the source to support upsert writes you might want to implement the `UpsertStreamTableSink`
rather than the `AppendStreamTableSink`. The `UpsertStreamTableSink` supports append writes
as well as updates and deletes by exposing the unique key fields of a `Table`.
